citizenM
A bit of a trek out of city center but close to the RAI convention center and the financial district, citizenM offers designer luxury on a budget. The hotel has 215 rooms with wall-to-wall windows, king-size beds, rain showers, free WiFi, VoiP, and a 'MoodPad' that allows you to control about anything electric in the room including the color of the interior lighting. There's a 24/7 food & beverage outlet serving anything from sandwiches to sashimi and a lounge area to relax in, with a nice selection of designer furniture of course.
